The Architectural Review Committee (ARC) is a group of owners who serve on a volunteer basis to ensure architectural consistency and compliance set forth in the Rim Rock Cove Governing Documents. Their role is to review projects before and after completion.

Grant County

Please note that due to recent Washington State Department of Labor and Industries (L&I) rulemaking, all persons performing manufactured home installations must be a certified installer, which now include homeowners seeking to install a manufactured home for their personal use. These rules took effect on January 31, 2022. The L&I rules require the placement of Washington State Installer Certification (WAINS) Tag to the home. Final inspections will not be performed or approved until the applicable tags are completed and affixed to the manufactured home. To view the rules as adopted by L&I, please review WSR 22-01-193 and WAC 296-150l-0110 (revised language online may be delayed).
